Is it normal to have parents that believe these things?
My parents are crazy, and here is some of the things that they do/think/believe which I've either overheard or they have told me directly:
My parents believe mermaids exist and my mother thinks its split from the evolutionary linage of humans (due to a show on tv).
My mother believes aliens created the "missing link" (due to a tv show).
They believe aliens visited us throughout history (I'm looking at you Ancient Aliens!! >:| ).
My father doesn't think evolution is a real thing and uses stupid arguments like "it's just a theory".
My mom thinks people close to her will always try to hurt her.
They think burning incense in the house will drive away spirits.
They believe that rubbing cannabis (weed) on the body will cure ANY illness or disease.
My mother literally thinks everyone is a psychopath (even my and my dad).
My mother thinks that Jesus and Muhammad are the same person.
I got my dad to admit that if something was written on a wall in ancient times (even if its a flying hippo with lazor eye beams) it exists.
My father thinks that whatever he says is right and admits that.
My parents think that the world is going to end at the end of 2012 and they have prepared for it.
------
Theres no telling how many other crazy things they believe, these are just the things that I've remembered. And whenever I try to challenge them on any of these things they get real upset and angry even if I'm real calm about things.
Then again, they've both told me stories of abuse from their childhood, so maybe that is a contributing factor (I know it is for my mom, at least as far as thinking everyone is out to get her).
I still love them but I sometimes can't stand being around them when they spout what I think is nonsense and push me off whenever I try to have a different opinion.
Is it normal?
